South Corning V STP - Secondary Wastewater Treatment in Corning, New York

South Corning V STP is a municipal wastewater treatment facility located in the City of Corning, Steuben County, New York. The plant serves a population of approximately 1,127 residents and operates under secondary treatment standards, which is the baseline requirement for municipal wastewater treatment in the United States under the Clean Water Act. The plant has a designed capacity of 757.08 million gallons per year and currently discharges 412.61 million gallons per year of treated effluent. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting EPA effluent guidelines for biochemical oxygen demand and total suspended solids. The treated wastewater is discharged into the Chemung River watershed, which flows into the Susquehanna River and ultimately reaches the Chesapeake Bay. The plant plays a key role in protecting local water quality and downstream ecosystems, including the Chesapeake Bay, which is a vital estuary for fish and wildlife.

The plant discharges into the Chemung River, a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient and pollutant loads from wastewater treatment plants in the watershed are closely managed to prevent eutrophication and hypoxia in the bay.
